LINER-TRIMMING GAGE.

To all whom it may concern:

Be it known that I, GEORGE S. BALL, a citizen of the United States,residing at l/Vashington, in the District of Columbia, have invented newand useful Improvements in Liner-Trimming Gages, of which the followingis a specification.

This invention relates to improvements in gages and more particularly togages for use in trimming type casting machine liners. In ejecting theliners from the machine, the ejecting mechanism forcibly strikes the endof the liner and frequently .mutilates said end. It is the main objectof this invention to provide a gage with which the liner end can betrimmed by filing, so that the mutilated portion of the liner mayberemoved.

Another object of the invention is to furnish a gage of. this characterconstructed to permit operation on a plane end liner or on a linerhaving a projecting lug at the end.

A still further object is to provide a liner trimming gage having anadjustable stop member and means for fixing the same for whole or halfem adjustments.

WVith the foregoing objects outlined and with other objects in view,which will appear as the description proceeds, the invention consists inthe novel features hereinafter described in. detail, illustrated in theaccompanying drawing and more particularly pointed out in the appendedclaims.

Referring to the drawing Figure 1 is a top plan view of the gage with aplane end liner located thereon.

Fig. 2 is a side view of the same.

Fig. 3 is a front end view.

Fig. 4 is a similar view but showing a liner having an end projection orlug.

Fig. 5 is a top plan view of the gage showing a liner, having an end lugplaced thereon.

Fig. 6 is a perspective view of an end of a plane end liner, a portionof the body of the gage, the end plate of the gage, and a screw forsecuring the end plate to the body.

Fig. 7 is a detail sectional view of the lug gage attachment used intrimming the, end of a liner having a projecting end lug.

Fig. 8 is a perspective view of the lug end of one type of liner.

In the drawing 1 represents a body plate of any suitable material,preferably metal. This plate is of oblong shape and it has a .1920.Serial no. 3 8,369.

longitudinal recess 2 in its upper, surface,

Specification of Letters Patent. Pate ted Nov. 22.11921.

Application filed March 24, i '7 i which merges into a groove 3 thatextends 3 along one side of the recess.

The distance between the inner surfaces 4 of the side walls 5 of therecess [is substantially the same as the width of a liner, so that astandard liner may be inserted in the recess and slid along the same.The groove 3 receives the longitudinalrib 6 which extends along one faceof one type oflinerT.

The top face of the body 1 is calibrated as shown at Send the distancebetween each two lines 9 is equalto a full em. A seriesof apertures 10are located between the lines 9 and each of these apertures is located afull em from adjacent apertures.

A gage stop, member 11 cooperates with the lines 9 and apertures 10for'gaging the length of material to be removed from a liner, and thismemberis provided on its underside with depending pins 12 and 13, theaxis of the former being located one em distance from the edge 14: and;the axis of the latter being arranged one-half em distance from the edge15. The pins are spaced two ems apart and the edges 14 and 15 arearranged three and one-half ems apart. The first edge is flush with theedge 16 of a lateral lug 17 and the edge 15 is flush with the edge 18 ofan oppositely extending lateral lug 19. 7

These latter lugs function, as gage stops for the transverse flange 20which extends across one face of a liner.

Located at the front end of the body is a guide stop plate 21, which hasfixed pins 22 that enter recesses in the forward face of the body, andthis plate is secured in position by means of a screw 23.

the body 1 is provided with a longitudinally extending hole 26 in which"is located a piston 27 provided at one end with an extension 28 thatcan be projected through a bearing 29 in the guide plate 21 to form apro jecting gage for the lug 30 which extends from the end of certaintypes of l1ners 7 The piston 27 is urged forward by a spring 31 and alockingdevice such as a screw '32 is used tosecure the piston inretracted or V: projected position.

. the mutilated end of the liner is moved forward untilfthe mutilatedportion extends through thep-late21 and projects beyond the forward faceof the same. The pins 12 and 13 arethen placed in the properholes 10 tobring the gage edge of one of the lateral lugs 17 or 19 into engagementwith the rear wall of the transverse rib 20 of the liner. As shown inFig. 1, the edges 15 and 18 are in alinement with one of the lines 9 butby. re

' versingthe member 11 and placing the pins in the same holes, the edges14% and 16 may be brought into alinement with the" axis of the holedirectly forward of said line 9.

- After the stop member 11 hasbeen set to hold the mutilated end of theliner in position beyond the front face of the plate 21, the mutilatedportion may be operated upon bya' file or the like for evening thedamaged end; As the plate 21 is of hardened steel or similarnon-abrasive substance, the-file or trimming implement will not affectthe same and the damaged end of the liner may be filed' down even withthe front face of the late. p The adjustable lug 28 is also of hardenedsteel or the like and in projected position, it alines withthe end lug30 of the liner 7 so that the damaged end of this type of liner may besmoothed or planed without mutilat in the lug 30.

Trom the foregoing, I believe that the construction and operation of mydevice will be readily understood without further description, and I amaware that various changes may be made in the constructlon shown withoutdeparting from the spirit of the invention as set forth in the followingclaims.

What I claim and desire to secure by Let ters Patent is 1. A device foruse in trimming a mutilated end of a type casting machine linercomprising a flat supporting plate for the liner provided at one endwith a non-abrasive plate having an aperture through which the mutilatedend of the liner is to project, and means cooperating with thesupporting plate and engageable with the other end of the liner forfixing the distance that the liner end is to project beyond saidnon-abrasive plate. j
